The architechtural framework for public cloud security

In cloud computing, at storage level, security provided to cloud by access control and data encryption key, and at network level installing virtual firewall and cloud service provider provides its internal storage for storing client's data using ips/ids to protect against attacks. Storing data in encrypted format is a common method of data privacy protection which causes a risk for the unauthorized disclosure of the user data. In this paper, discuss the introduction of cloud computing, framework for public cloud security, cloud service providers, authentication mechanism and attributes. There all different mechanism is explained for providing privacy in public cloud services on basis of the desired and proposed architecture.
